Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 0235 0236 0236 130 0551 0551 0551 190 B. Proton Events: None C. Geomagnetic Activity Summary: The geomagnetic field was quiet to unsettled. The high speed coronal hole stream that produced the minor disturbance over the past several days has declined considerably. Solar wind speed peaked yesterday near 800 km/s, but gradually decreased to 500 km/s by the end of the period. D. Stratwarm: None E. Daily Indices: (real-time preliminary/estimated values) 10 cm 099 SSN 081 Afr/Ap 006/007 X-ray Background A9.0 Daily Proton Fluence (flux accumulation over 24 hrs) GT 1 MeV 1.2e+06 GT 10 MeV 1.3e+04 p/(cm2-ster-day) (GOES-11 satellite synchronous orbit W101 degrees) Daily Electron Fluence GT 2 MeV 1.30e+09 e/(cm2-ster-day) (GOES-12 satellite synchronous orbit W75 degrees) 3 Hour K-indices: Boulder 3 1 1 2 2 2 2 1 Planetary 3 1 1 3 3 2 2 1 F. Comments: The greater than 2 MeV electron fluence at geosynchronous orbit was at very high levels.
